A device used to lengthen the distance between the motorcycle’s rear wheel axle and the swingarm pivot point is a modification commonly applied to motorcycles. This alteration is achieved through the installation of aftermarket components designed to replace or extend the original swingarm. An example of its application is on drag racing motorcycles, where increased wheelbase enhances stability during high-speed acceleration.
The primary benefit of this modification is improved stability, particularly during acceleration. A longer wheelbase resists wheelies and provides a more predictable handling characteristic at higher speeds. Historically, this modification gained popularity in motorsports to enhance performance. Its use enables riders to manage high horsepower output more effectively and maintain control during critical moments.
